PearTree is a browser-based phylogenetic tree viewer for exploring and annotating evolutionary trees. Developed for genomic epidemiology, it displays large NEXUS and Newick files with rich visual annotations and is positioned as a successor to FigTree. The software runs entirely in the browser, or as a native desktop application on macOS, Windows and Linux.
A defining feature of the tool is its handling of data. No data is uploaded to any server: all processing is performed locally on the user's machine. This local-only approach is a stated priority for the company, and reflects a broader emphasis on data privacy in scientific research software.
PearTree works on open source software and peer-to-peer software development solutions. Its technical domains include bioinformatics, phylogenetics, data visualization, web browsers and cross-platform desktop applications. The company serves users in bioinformatics, genomics, evolutionary biology and related research fields.
